Caecidotea is a genus of crustaceans in the family Asellidae. It contains the following species: [2]
Sphaeromatidae is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones. The family includes almost 100 genera and 619 known marine species. Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.
Crangonyx is a genus of crustacean in family Crangonyctidae. Crangonyx species can live in marshes, savannas or swamps as well as caves. It contains the following species:
Gammarus is an amphipod crustacean genus in the family Gammaridae. It contains more than 200 described species, making it one of the most species-rich genera of crustaceans. Different species have different optimal conditions, particularly in terms of salinity, and different tolerances; Gammarus pulex, for instance, is a purely freshwater species, while Gammarus locusta is estuarine, only living where the salinity is greater than 25‰.
Lirceus is a genus of isopod crustaceans in the family Asellidae that live in southern Canada and the eastern United States as far west as the Great Plains. Of the 15 species in the genus, two are listed as either endangered (EN) or vulnerable (VU) on the IUCN Red List.
Proasellus is a genus of isopod crustaceans in the family Asellidae. Two of its species, P. parvulus and P. slovenicus, are Slovenian endemics which are listed as vulnerable species on the IUCN Red List.
Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. The majority of the listed species are endemic to North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); one species, S. lucifugus, is extinct.
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter", which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body. Ceratothoa oestroides is one of the most devastating ectoparasites in Mediterranean aquaculture. Around 40 genera and more than 380 species of cymothoid are recognised. Species of the Cymothoidae are generally found in warmer waters and rarely in the cool and cold climates.
The Asellidae are a family of isopod crustaceans, one of the largest families of freshwater isopods, living in both epigean and hypogean habitats in North America and Europe.
The Cirolanidae are a family of isopod crustaceans, including these genera:
The Bopyridae are a family of isopod crustaceans in the suborder Cymothoida. There are 1223 individual species contained in this family. Members of the family are ectoparasites of crabs and shrimp. They live in the gill cavities or under the carapace where they cause a noticeable swelling. Fossil crustaceans have occasionally been observed to have a similar characteristic bulge.
Harriet Richardson Searle was an American carcinologist. She was known as the first lady of isopods and was one of the first female carcinologists, with only Mary Jane Rathbun before her.
Cirolana is a genus of isopod crustaceans.
Nerocila is a genus of parasitic isopod crustaceans, with 11 species, which have been found parasitizing Indian marine fishes.
Caecidotea acuticarpa is a species of crustacean in the family Asellidae. It is endemic to Kansas and Oklahoma in the United States.
Caecidotea adenta is a species of crustacean in the family Asellidae. It is endemic to Oklahoma in the United States.
Caecidotea bicrenata is a species of isopod in the family Asellidae. It is endemic to Eastern United States.
